Description

technical field [0001] The invention belongs to the field of pharmacy, and relates to a compound preparation of fasudil and vardenafil and a preparation method thereof, which are used for the treatment of pulmonary hypertension. Background technique [0002] Fasudil [hexahydro-1-(5-isoquinolinesulfonyl)-homopiperazine, Fasudil] is a Rho kinase inhibitor. Its molecular weight is 327.83 and its molecular formula is C 14 h 17 N 30 2S·HCl, structural formula: [0003] [0004] Studies have confirmed that the Rho kinase pathway is one of the important pathogenic pathways leading to pulmonary artery constriction and pulmonary vascular remodeling in patients with pulmonary arterial hypertension. For pulmonary hypertension, fasudil can reduce the activity of Rho kinase, inhibit the contraction of pulmonary artery vascular smooth muscle, dilate pulmonary arteries, reduce pulmonary artery resistance, and reduce pulmonary arterial pressure. [0005] Vardenafil (Vardenafil) is t...
